GET_SERVER_STATUS
Report the connector as reachable
The only capability with nothing behind it. Status comes from the connection itself: an authenticated WebSocket, a completed handshake, and heartbeats still arriving. There is no method to write and no query to configure, on either family.
Announce it once the connector reaches the point where it can stay connected. Nothing breaks if you leave it out — status is read from the connection regardless.
Announced, not implemented
Because status follows from the connection, Admin → Game Servers leaves this out of Game server support entirely. A row reading "not implemented" beside a dashboard showing the server online would be a claim about a feature that is plainly working.
Verification
Connector check passes it whenever the connection is live and the handshake has completed — which is necessarily true if the check ran at all.
